FOUNTAIN-PEN.`

Specification of Letters Patent. Application sled august 14.1906. serial No. 330.547.

Patented July 23, 1907. 4

To all whom itl may concern:

Be it known that I, WILLIAM K. HOLMES, a citizen of' proved Fountain-Pen, o which the following is a full,`

clear, and exact description.

My invention relates to that class of fountain pen in which the ink is contained in a sack, and wherein the filling of the sack is accomplished by contracting the same and then permitting it to expand.

The purpose oi my invention is. to so construct` the pen thatI simple and conveniently operated means are employed for pressing or collapsing the sack simultaneously approximately its entire length, the pressure being brought to bear parallel with the sack and in a uniform manner; Thus the greatest possible amount of air is forced from the sack, and when it is permitted to expand a maximum quantity of ink is drawn therein.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

VReference is to be had to the accompanying drawings forming a part of this specification in which similar characters of reference indicate corresponding partsl in all the figures.

Figure 1 is a" longitudinal section' through the improved pen, showing its parts in normal or carrying position and the sack as fllled; Fig. 2 is also a 'longitudinal section through the pen, but the pen is shown inverted, or in position for writing or filling and the sack is shown empty and compressed; and Fig. 3 is a transverse section taken substantially on the line 3-3 of Fig. l.

p A represents the barrel of the pen, B the customary plug provided with Ameans for retaining in position a pen nib B and a feeder B2, the latter being of any ap7 proved type.

C represents the sack, which is made of soft rubber or equivalent material, and its length is nearly the length of the barrel A. The end of the sack presented to the plug B is open, and said open end of the sack is attached to the plug in any suitable or approved manner in such a way that the ink can be drawn up by the sack when it is compressed, through the opening in the plug in which the pen and feeder are introduced. Otherwise the sack C is closed.

When the sack, is filled with ink, or is' otherwise expanded, it fits somewhat snugly to the inner wall of the barrel A, as shown in Fig. 3. A sleeve 10 is introducedinto what may be termed the head portion ofthe barrel,

or the end which is opposed to that carrying the nib,

tition 11 is formed, which constitutes the closing element for the head end ofthe barrel7 and in said partition, 11 aslot 12 is produced.

A needle 13, preferably rectangular in cross section is employed to press or collapse the sack C, asis shown in Fig. 2. Said needle is of a length practically corresponding to the length of the sac-k O; and normally, that is when the sack is expanded or is filled, the needle 13 lies between the outer wall of the sack C and the opposing inner wall of the barrel A as is clearly shown in Figs. 1 and 3.

The needle 13 is provided with a straight shank 14 that extends longitudinally within the sleeve 10; and at the upperend of the straight portion of said shank 14 a collar 17 `is secured, which serves to limit the outward movement of said shank. The shank 14 of the needle 13 is pivotally connected with a link 15,

and said link is pivotally .attached to the sleeve 10` as is shown at 16 in Figs. 1 and 2.

When the needle 13 is in its normal position shown in Fig. 1, the link inclines downward in direction of the sack; but when said needle is at the end of its throw, or is in position to completely collapse or firmly press together theopposing walls ofthe sack C, the link 15 is in the horizontal position illustrated in Fig.

l2. The shank 14 of the needle is provided with an extension 18, which connects with the inner or straight portion of the shank just outside of the collar 17. Said extension 18 from the shank is given an outward inclination in direction ofthe side of the barrel, so that it is at more or less of an acute angle to the straight shank section 14. At the outer end of the shank extension 18 a recess 19 is produced in one longitudinal edge, adapted to receive a finger nail of the operator when the shank of the needle is to be drawn outward fromA the position shown in Fig. 1 to the position illustrated in Fig. A2. The usual cap D is provided for the pen.

When the needle 13 is in its normal position shown in Figs. 1 and 3, the outer or slotted end of the extension 18 of the needle shank extends just out beyond the partition 11, and is prevented from being accidentally caught and drawn outward by the'wall of the 'sleeve 10 that extends out beyondthe said partition. When the sack C is empty, or practically so, the extension 18 of the shank 14 is grappled and is drawn outward', causing the needle tof travel toward the opposite side of the barrel parallel with the wall of the barrel yand parallel with the sack, whereby theand will exert a maximum of suction on the ink into' Having thus described my invention, I claim as mew, and desire 'to secure by Letters Patent,-

1. In a fountain pen a barrel, a plug at one end thereof adapted to carry a feeder and a nib, a sleeve in the other end of the barrel, a sack located within said barrel and having one end connected with the plug, a needle"within the barrel between the wall thereof and the sack, and a link normally lying -alongside the needle and pivoted `hy one end thereto and by the other end to the sleeve, whereby the movement of the needle with respect to the barrel will move said needle to compress the sack.

2. In a fountain pen a barrel, a plug. at one end thereof, a sleeve on the other end of thebarrel, a sack within the 4barrel and connected with the plug, a needle within the barrel between the wall thereof and the sack, a link normally lying alongside the needle and pivoted by one end thereto and by the other end to the sleeve, whereby the movement of the needle with respect to the barrel will move the same to compress the sack, said needle extending ouside of the barrel and having a notch whereby to manipulate the same.

3. In a fountain pen, a barrel, a plug at one end, a partition at its opposite or head end, havingr a slot therein, a straight needle having a straight shank located within the ysaid barrel and adapted for parallel movement from one side of the barrel in direction of the opposing side and for parallel action on the said sack, a link connecton'between the shank of the needle and the barrel, said link being located within the barrel, and an extension fronrthe outer end of the shank, adapted to pass through the slot in the said partition, which extension is at an actute angle to the main or straight portion of the shank, and in the normal position of the said needle theouter portion of the shank extension lies just-outside of the' head partition within the surrounding. portion of the barrel. l

4. In a fountain pen, a barrel, a plug at one end, a partition at its opposite or head end, having a slot therein, a straight needle having a straight shank, located within the said barrel and adapted for parallel movement from one sdeof the barrel in direction of the opposing side and for parallel action on said sack, a link connection between the shank of the needle and the barrel, the link` being located within said barrel, and an extensionfrom the outer end of the shank, adapted to pass through the slot in said partition, which extension is at an acute angle to thevmain or straight portion of the shank, and in the normal position of said needle thelouterport'ion of the shank extension lies just outside of the head partition, the said extension from the needle shank being provided with a notch iny one of its edges adjacent to its outerend, and a stop lo cated on the needle shank proper, which stop limits the outward movement of the needle. 5. In a fountain pen a barrel, a plug at one end thereof, `a sleeve in the other end thereof, a sack within the barrel and connected with the plug, a needle within the barrel between the wall thereof and the sack, a link normally lying alongside the needle pivoted by one end thereto and by the other end to the sleeve whereby the movement of the needle with respect to the barrel will move the saine to compress the sack, the end of said needle extending flush with the end of the sleeve when in-normal position and being provided with a notch whereby to withdraw it from the sleeve.

In testimony whereof I have signed my name to this specification in' the presence of two subscribing witnesses.

WILLIAM K. HOLMES.
